ABSTRACT:
Optically active p-hydroxyphenylglycine is manufactured by inoculating a supersaturated solution of a p-hydroxyphenylglycine sulfonic acid derivative salt comprising a mixture of the two optically active enantiomers of said salt with an optically active enantiomer of the same salt, said mixture being either racemic or else one in which the predominant enantiomer is that of the inoculant. In this manner the enantiomer having the form of the inoculant is selectively crystallized. The selectively crystallized salt is thereafter treated for removal of the sulfonic acid derivative.
